FOLDING PAPER BOX.

Specification of Letters Patent. Pgmtqgnted Apr, 29, 1919,

Application filed August 17, 1918. Serial No. 250,265.

0 all whom it may concern: i i

Be it known that I, ABBIE Gouoom'a citizen of the United States, and resident of the city of Belvidere, county of Boone, and State of Illinois, have invented certain new and useful Improvements in Folding Paper Boxes, of which the following is a specification. i

My invention relates to folding paper boxes and consists of a box having an improved form of construction which adds to its strength and stability and also makes it much more difficult to become loosened and opened, thus largely preventing the possibility of accidental opening of the box and at the same time making it unnecessary to place either any wrapping about the same or a securing cord. i

The object of my invention is to provide a folding box which is more secure in its locking arrangements and one which is strong enough to stand shipping or handling without danger of its becoming crushed and also without danger of its becoming opened, even if not secured by a wrapping paper or cord. My invention comprises the novel constructions and combinations ofparts which will be herein described and then particularly pointed out by the claims,

In the accompanying drawings, I have shown a box having the. construction which I now prefer to use.

Figure 1 shows the blank from which the box is made before it has been folded.

Fig. 2 shows the completedbox in per spective, with one of the top holding and locking flaps completely closed and the other not entirely closed down.

Fig. 3 is a transverse section of a closed box.

Fig. 4 is a side view of one corner of the box, showing the manner of locking and holding the top locking flaps.

The center or bottom section 1, of the box is provided at each edge with a side section as 2, 20, and 21. One of these sections. 20, has the main top section 3 extending from its outer edge. This top section preferably has a short flap 30 extending from its outer edge and a tongue 31. The opposite side section 21, is preferably provided with a flap 22 extending from its outer edge, which forms a supplemental and partial top section. While this flap is deemed desirable it might in some cases be omitted but as it 'two edges of the bottom section.

' opposite edge.

requires no more pasteboard to secure this flap than it does from which to make the interlocking flaps 4 and 40, it would pref erably be used in all cases where these flaps 4 and 40 were employed.

The side sections 2 extend from the other From each of these extends a flap 5 which is designed to fold over the top section 3 and to act as a means for holding the same securely down. From each end of these topholding flaps 5, extend flaps 6, which flaps are each provided with a locking tongue 60. Thi locking tongue is provided with two notches, 61 and 62 at opposite side edges thereof. The notch 62 which is at the edge adjacent to the flaps 4 or 40 is nearer to the line of fold or hinge between the flap 6 and the flap 5, than is the notch 61 on the The locking tongue is also cut so that its side edge 64 which, as it appears in the blank, is next to the flap '4 or 40, is slightly removed from the adj acent edge of the said tongue or flap 4.

The tongues or flaps 4 and 40 are pro vided with coniplen'iental locking tongues 41 and slots 42, so located that when the side sections are folded up and these flaps 4 and 40 are folded inward, the tongue 41 will enter the slot 42 and lock it together, thus forming a reinforcement or stiffening for this side wall of the box. The tongue 41 is constructed similarly to the tongue 60, which has just been described. The tongue-receiving slot 42, it will be noted, is, in all cases, placed in a diagonalor inclined position, this incline corresponding substantially with the inclined line connecting the bottoms of the notches 61 and 62 which appear at opposite edges of the tongue.

In placing the tongue in the notch, end 64 is first inserted in the slot. The distance between thebottom of the slot 62 andthe outer end of the tip 63 is just enough less than the length of the slot to permit the tongue to fully enter the slot when the tongue has been moved to one side enough to bring the inner end of the slot 42 down to the bottom of the notch 62. In this position the two parts 4 and 40 are laterally displaced. When these parts are brought back into alinement with each other, the tongue 63 passes to the opposite side of the flap 40 and the two parts are then locked so that they cannot be separated except by a corresponding lateral displacement, or by tea-ring one of the parts. As the two flaps 4L and 40, after the box is set up, lie inside the box and cannot be laterally displaced, there will be no separation without tearing. The slots 23 which are formed in the end of the side sections 20 and 21, are similarly placed in inclined positions and cooperate with the tongues 60 carried by the top holding or locking flaps 5, in the manner just described.

The manner of placing these in position is clearly shown in Figs. 2 and 4. lVhen the flap 5 is turned down, the end 64 of the tongue first enters the slot 23. In order to get the bottom of the notch 62 up to the end of the slot 23 it is necessary to move the flap 5 and its connected side section 2, outwardly from the box enough to permit the tip 63 to pass through the opposite end of the slot. After it has passed through the slot, the flap 5 with its attached side sections 2 is then pressed up to the box and the tip 63 passes inside of the side section 20 or 21, as the case may be, and is engaged so that the top flap 5 cannot be raised without some means is provided for getting the tip 63 to return through the slot. This can only be done by placing a knife or some small object through the slot, so as to engage the tip 63 and guide it outward through the slot. This also requires an outward sliding movement of the flap 5 and as this action will never take. place automatically or accidentally, the box will not become accidentally opened.

The flaps 5 While giving stiiiness and strength to the box, also serve to securely hold down the main top section 3. By the action of the flaps 6, which bear against the outer edges of the box and also by reason of the downwardly turned narrow flap 30, the

oppositesides of the box are held securely against separation. The box is a tight one having no slots communicating freely between its interior and the exterior. It is also strong and stiff and requires nothing in the way of a wrapper or a cord to prevent its coming open. Its use will, therefore, save these small items of expense.

What I claim as my invention is:

1. A folding paper box having a full top section provided with means for interlocking engagement of its swinging edge with the box side, and flaps extending from the other two sides of the box and folding over the side portions of said top section, the ends of said flaps having extensions folding down and having interlocking engagement with the other side sections of the box.

2. A folding paper box having a bottom section, side sections folding upward from the edges of the bottom section, a full top section connected with one side section, means for connecting the outer edge of the top section with the opposite side section, locking cover sections extending from the outer margins of each of the other two side sections andfolding over the side parts of the top section and tuck sections extending from the ends of said locking cover sections and each provided with a locking tongue notched on its side edges, the adjacent side sections being provided with slots adapted to receive the said locking tongues.

3. A folding paper box having a central or bottom section, side sections at each edge of the bottom section, a top section extending from one side section, and having a tongue extending from its outer edge, the opposite side section having a slot for the reception of said tongue, the other two side sections having extensions from their ends of like width therewith and compleinentally provided with tabs and tab-receiving slots, the same side sections having cover holding flaps extending from their outer edges, said flaps also having locking sections extending from their ends and provided with looking tabs, the adjacent side sections having slots for the reception of said tabs.

Signed at Belvidere, Illinois, this 31st day of July, 1918.
